Darwin, C. R. to Eyton, T. C.

4 Mar [1872]


Thanks for facts about ducks.

Thinks TCE will be converted to principle of evolution if he continues testing facts for and against it. Natural selection is another question.


Down, | Beckenham, Kent. [9 Devonshire Street, London.]

March 4th

Dear Eyton

I know that you disbelieve in evolution, & therefore it is all thekinder your sending me the note about the Ducks. It is curious howmuch easier it seems to be for plumage to alter than any other visiblecharacter.f2

If you continue testing facts as favouring or opposed to the principle ofevolution, I think that you will become a convert; but whether you willbelieve in natural selection is another question.— If you do not,you will, I believe, find it impossible to account for the innumerableadaptive structures everywhere to be seen.— It is really astonishing howrarely I now meet with any naturalist who does not admit evolutionunder some form.—

Pray believe me, dear Eyton | yours sincerely | Ch. Darwin
